Somerfield (/ˈsʌmərfiːld/; originally Gateway) was a chain of small to medium-sized supermarkets operating in the United Kingdom. The company also previously owned the Kwik Save chain of discount food stores. The company was taken over by the Co-operative Group on 2 March 2009 in a £1.57 billion deal, creating the UK's fifth-largest food retailer. The Somerfield name was replaced by the Co-operative brand in a rolling programme of store conversions ending in summer 2011.
